I put in a fantastic fan over the summer. Great investment. Wireless is the way to go. I agree with Accoster
. The roof work was the hardest part.
By the way, if you have the beige (almond) roof sealant, no one sells it. I called Crossroads to buy it direct and customer service sent me two tubes and couldnt figure out the price, so they sent them fedex and didnt charge. Good guys over there. I like to tinker and do my own repairs, the customer service guys are always willing to help me out.
Anyways, fan was a great investment. Got it for 212 on Amazon. Camperworld wanted over 300.
